Two shapes of viral capsids

WebSome viral capsids are simple polyhedral “spheres,” whereas others are quite complex in structure. In general, the shapes of viruses are classified into four groups: filamentous, isometric (or icosahedral), enveloped, and head and tail. Filamentous viruses are long and cylindrical. Many plant viruses are filamentous, including TMV. WebMar 3, 2016 · Capsid Shape is one way to classify viruses, along with the composition of the capsid.
